Hello, as reports emerge that four busloads of civilians managed to leave Mariupol on Wednesday, we hear from UN humanitarians who continue to plead for safe and sustained access to the besieged city.

Also in this week’s show, we visit the UN Satellite Centre UNOSAT, which is tracking the devastation caused by shelling across Ukraine – how does it fit into the international calls for accountability, following Russia’s invasion on 24 February?

Away from Europe, the Horn of Africa needs all our attention too, say aid agencies, who’ve raised the alarm – once again – over the many millions of people who face catastrophic food insecurity after three failed rainy seasons.

Stay with us too for closing comments about defiant poets in Spain, Russia and in space – sort of - from our regular guest, Solange Behoteguy-Cortes.
